Abstract
A wire cut electrical discharge machine (10) has two machining fluid supply systems respectively for supplying machining fluid is having different qualities to the machining section (14) thereof, namely, a rough-machining fluid supply system (20) and a finish-machining fluid supply system (60). The rough-machining fluid supply system (20) has a first machining fluid quality regulating circuit comprising a first machining fluid tank (26) having a filtering device (3) for filtering powdery chips, a specific resistance detector (34), a cooler or heater (42, 44), an ion exchange device (52) and pumps (40, 58), and the finish-machining fluid supply system (60) has a second machining fluid quality regulating circuit comprising a second machining fluid tank (66), a specific resistance detector (74), an ion exchange device (92), a cooler or heater (42, 44) and pumps (40, 98). A machining fluid of a quality appropriate for the purpose of wire cut electrical discharge machining, namely, rough machining or finish machining, is supplied to the machining section.
